About This Guide xxi
Chapter 7, 802.1 Configuration Menu Screens, describes how to access the Spanning Tree
Configuration Menu, 802.1Q VLAN Configuration Menu, and 802.1p Configuration Menu,
screens. This chapter also introduces and describes how to use the Spanning Tree screens to create
a separate Spanning Tree topology for each VLAN configured in the module.
Chapter 8, 802.1Q VLAN Configuration Menu Screens, describes how to use the screens to
create static VLANs, select the mode of operation for each port, filter frames according to VLAN,
establish VLAN forwarding (Egress) lists, route frames according to VLAN ID, display the
current ports and port types associated with a VLAN and protocol, and configure ports on the
switch as GVRP-aware ports. VLAN classification and classification rules are also discussed.
Chapter 9, 802.1p Configuration Menu Screens, describes how to use the screens to set the
transmit priority of each port, display the current traffic class mapping-to-priority of each port, set
ports to either transmit frames according to selected priority transmit queues or percentage of port
transmission capacity for each queue, assign transmit priorities according to protocol types, and
configure a rate limit for a given port and list of priorities.
Chapter 10, Layer 3 Extensions Menu Screens, introduces and describes how to enable or
disable IGMP (Internet Group Management Protocol, RFC 2236) on selected VLANs, or globally
on all VLANs that are available.
Chapter 11, Module Statistics Menu Screens, introduces and describes how to use the statistics
screens to gather statistics about the switch, interfaces, RMON, and HSIM/VHSIM and, if the
device is a repeater, repeater statistics.
Chapter 12, Network Tools Screens, describes how to access and use the Network Tool screens.
This chapter also includes examples for each command.
Chapter 13, VLAN Operation and Network Applications, introduces VLANs, describes how
they operate, and how to configure them using the Local Management screens described in
Chapter 8. Examples are also provided to show how VLANs are configured to solve a problem and
how the VLAN frames travel through the network.
Appendix A, Generic Attribute Registration Protocol (GARP), describes the switch operation
when its ports are configured to operate under the Generic Attribute Registration Protocol (GARP)
application – GARP VLAN Registration Protocol (GVRP).
Appendix B, About IGMP, introduces the Internet Group Management Protocol (IGMP), its
features and functions, and describes how it detects multicast routers.
NOTE: There is a global setting for GVRP that is enabled by default. However, this
setting is only accessible through a Management Information Base (MIB).
